Box-LABELING MACHINE.

Specification of Letters Patent.

Patented July 17, 1906.

Application filed October 5, 1905. Serial No. 281,387.

T all whom, it indy concern:

Be it knownv that I, JOHN F. KACHLINE, a citizen of the United States, residing in the city of Reading, county of Berks, State of Pennsylvania, have invented certain new and useful Improvements in Box-Labeling Machines, of which the following is a specification.

My invention relates particularly to boxlabeling machines such as shown and described in Letters Patent No. 795,621, issued to ine July 25, 1905; and it consists in certain improvements whereby the pasted labels are more satisfactorily controlled in applying them to the boxes.

The accompanying drawings illustrate the invention as applied in preferred form to a machine such as is fully set forth in my prior patent referred to, and is particularly described and pointed out in the accompanying specification and claims.

Figure 1 is a sectional elevation showing' a portion of a box-labeling machine having my improvements applied thereto. Fig. 2 is a plan view of the same. Fig. 3 is a partial end elevation looking in the direction of the arrow 3, Fig. 1.

As shown and described in my patent above mentioned, the pasted label-strip is drawn through feed-rolls 53 and 70 and pushed into position on the box between the cutter-knives 74 75 to be cut off and pressed upon the box by the presser-plate 76.

I have found that in using wide labels it is more satisfactory to provide for positively supporting and guiding the label during the operation of applying it to the box, so as to insure its being accurately and smoothly pasted thereon. In order to insure this positive support of the label above the box after its passage between the knives, I provide a horizontally-movable finger-frame 1, having strip-supporting fingers 2 extending under the feed-roll 7 0 and knife 74 and above the box-supports 86. This fingerframe 1 is supported in a slide-block 3, moving on guide-rods -1 and 5, so that the fingers 2 may be advanced or retracted over the box-supports S6. The fixed guide-rods L1 and 5 are carried by cross-braces 10, Secured to the side frames of the machine. The slide-block 3 has a rearwardly-extending toothed rod 6, which is engaged by a springpressed catch 7 to hold it in advanced position, and a spring 9 is provided to retract said block and finger-frame when the catch 7 is raised.

On a drive-shaft S, mounted in the frame of the machine, is fixed a crank-arm 11, having a slot 12, and a block-engaging roller 13 is adj ustably secured in said slot to vary the eHective stroke of the crank. The roller 13 bears against the face 14 of the slide-block 3 and with each revolution of the shaft 8 slides said block 3 along the guides 4 and 5 to advanced position. A separate cam-arm 15 on Isaid shaft 8 is set to bear against a pin 16, attached to the spring-catch 7, and ,raise same to release the ratchet-rod 6 and permit the spring 9 to retract said slide-block 3.

I'have found it desirable to move the fingers 2forward in a plane somewhat above the level of the box-supports S6 and to thereafter lower them to rest on said supports just before the withdrawal of the fingers by the spring 9. To accomplish this, I mount the finger-frame 1 on posts 17 and 1S, with a spring 19 arranged to normally keep said rack in raised position. The post 18 is eX- tendeddownward through the block 3 and has a notch 20 and a lateral projection 21. A pivoted lever 22 bears on said projection 21 and extends into the path of the roller 13. At the end of the forward movement of the block 3 the roller 13 bears down on said lever 22, which lowers the post-18 and the attached finger-frame 1 and fingers 2. A latch 23, having a pin-rod 24 engaging in the notch 20, holds the fingers in such lowered position. Upon the release of the ratchet-rod the block 3 is withdrawn by the spring 9, and the pinrod 24 is released from the post 18 by coming in contact with the guide-rod brace 10, so that the spring 19 will reraise the fingers to normal position. Y

In order to hold the label in position on the box during the withdrawalof the fingers 2 before the presser-plate comes into action, I provide one or more clamping-plungers 25 in the presser-plate, normally pressed downward by the springs 26. The shafts of said plungers, as shown, are notched at 27 for engagement of a catch 28, pressed into contact therewith by a spring 29, so as to lock them in raised position, said catch being released during the downward movement of IOO upon the box-supports 86.

the presser-plate by means of a'release-pin 30, which engages a lever 31 on the frame of the machine, so that the plungers shall first press the label against the box sufficiently to hold it during the withdrawal of the fingers 2, which latter are of course arranged out of line with the plungers.

The operation of my machine is as follows:

The feed-rolls drawthe pasted. label-strip forward and feed the same between the knives. As the strip is fed forward the fingers 2 are advanced with it as desired by the action of the crank 1l, thus supporting the projected label in level position and just above the box. The fingers 2 are then lowered at the endof their forward movement to lay the strip on the box by the crank ll pressing down the lever 22, bearing on the rod 18, the downward movement of the knife 75 and presserplate 76 simultaneously causing the plungers 25 to press the labels against the box between the fingers 2 to hold the same in position. The fingers 2 arenow released bythe camarm 15 raising the catch 7, and the spring 9 draws them back, while the release yof the catch 23 at the end of the rearward movement caused them to be raised for the next advance movement. The continued downward movement of the knife and presserplate cuts the label from the strip and presses the same upon the box placed in position The downward movement of the presser-plate forces rthe plungers back into the presser-plate'until the notches register with the spring-catch which locks them in raised position. The presserplate 76 is then released, and the springs 7 S raise it for the next succeeding cut.

It will be readily understood that modifications in the detail construction may be readily devised that will be within the spirit of my invention, the novel features of which are pointed out in the subjoined claims.

What I claim is- 1 In a machine for labeling boxes the combination with the box-support and presserplate and label-strip feeding and severing devices, of a strip-support and means for periodically projecting the same between the box-support and presser-plate, substantially as set forth. v

2. In a machine for labeling boxes the combination with the box-support and presserplate and label-strip feeding andjsevering devices, of a strip-support and means for moving the same forward with the labelstrip and for withdrawing it prior to the pressing operation, substantially as set forth. U3. In a machine for labeling boxes the combination with the box-support and presser- Vplate and label-strip feeding and severing devices, of a strip-support, means for periodically projecting the same between the boxsupport and presser-plate, means for lowering the projected strip-support, and means for withdrawing the same prior to the pressing operation, substantially as set forth.

4. In a machine for labeling boxes thecombination with the box-support and label-strip feeding and severing devices, of a presserplate with spring-pressed clamping devices, strip-supporting fingers movable between said box-support and presser-plate, and means for withdrawing said fingers substantially as set forth.

5. In a machine for labeling boxes the combination with the box-support and label-strip feeding vand severing devices, of a presserplate with spring-pressed clamping devices, strip-supporting lingers movable between said box-support and presser-plate, means for lowering the projected fingers, and means for withdrawing the samefsubstantially as set forth.

6. In a machine for labeling boxes the oombination with thebox-support and presser- 'plate and label-strip feeding and severing devices, of a horizontally-movable slideblock, a strip-support movable withv said block, means' for reciprocating said block, and means for moving said strip-support vertically, substantially as set forth.

In testimony whereof I aflix my signature -in the presence of two` witnesses.
